Planetary Geophysics | Dr. Douglas Hemingway

In this episode, I enjoyed a wonderful conversation with Dr. Douglas Hemingway, a world-renowned Planetary Geophysist and Robotics/Systems Engineer who makes groundbreaking discoveries of geologic phenomena on Planetary Bodies within our Solar System. Dr. Hemingway's work stretches many topics, from Paleo-Oceans on Mars to the Formation of Geysers on Enceladus that can reach up to 130km long (for scale, that's almost the distance from Portland to LA). His discoveries are monumental in pursuing a better understanding of our Solar System and the Planetary Bodies within. His field of research will only continue to grow as our ability to explore space increases. Dr. Hemingway also helped build planetary Rovers and the International Space Station during his time as a Robotics and Systems Engineer in industry. During the interview, Dr. Hemingway explained topics such as how Planetary Bodies produce magnetic fields, the formation of Enceledus' Tiger Stripe Formations, the differences, and similarities between icy moons like Europa, Enceladus, and Ganymede, evidence for Ancient Martian Oceans, what are Lunar Swirls and how they form, the mechanics of Space Weathering, and much much more.Mentioned Articles, Sources, and Further Reading:Black, B.
